Repelling Ants and Other Insects With Vinegar
Vinegar is exceptionally useful in the garden for deterring insects. It is difficult to find a better, more environmentally safe substance.
Keep ants away from plants in your garden by making a circle around them with vinegar. Just dribble a generous stream around each plant. This will act as a barrier to wandering ants.
CAUTION: - Do not put vinegar around peony plants that are budded. Peonies need ants to remove a sticky substance from the bud so the bud will open to a flower.
Place small dishes of vinegar with sprigs of lavender in it around outdoor living areas to repel flies.
